Chrome vs Safari is different :( pls helppp

Hello, I’m in the process of creating my portfolio and I have it setup perfectly for Chrome but when I view it on Safari a lot changes. The cursor starts acting weird and disappears and the bottom nav image overlaps the entire thing. Can someone please help me? I just got laid off and i need to start applying to jobs with this but it’s not working at allllll. :frowning:
